查询词典 Labrador Current

From the special viewpoint of information and belief, our analysis finds that through refusing free information the current self can restrain future selves' ill tendency when the external information are static stock. This conclusion can be supported by finite or infinite horizon model as well. When external information are dynamic flow, current self's controlling instrument is forestallment, sometimes he would invest even under negative net present value. Selective memory can also serve as a controlling instrument, current self selectively convey information to future selves.

本文选取了信息与信念这一独特视角，深入探讨现期自我的控制手段，研究发现：当信息为静态的存量时，现期自我可通过拒绝外生信息克制远期自我的不良倾向，该结论在有限期或无限期模型中均成立；当信息为动态流量时，时间不一致矛盾将侵蚀等待的期权价值，现期自我会以抢先行动的方式拒绝进一步信息，甚至采取NPV为负的行动；现期自我也可通过选择性记忆向远期自我传递信息，这就是信息传递阶段的控制手段。

AlN MSM devices were fabricated on AlN epitaxial thin film deposited on GaN/Sapphire substrates using helicon sputtering system at the low temperature of 300°C. The device characteristic was found to be improved by in situ metallization of Al electrodes. The extremely low dark current (1.39pA at 20V), the ideal factor (1.0125) and the Schottky barrier height (0.916eV) are superior compared to those of AlN MSM in the literature. When the device was illuminated by the 150W D2 lamp, the ratio of the induced photocurrent to dark current is more than 2 orders of magnitude. The illumination effect also shows the linear relationship between the radiation power and the photo current for the MSM devices, indicating the potential applicability for deep UV sensors.
